That's quite impressive. I don't know if it can be called a paradigm shift, but I think there is more potential for growth with this approach than in current CMOS technology.
I wonder, since the electrodes can be switched on and off so quickly, if this might be used as an alternative to high speed sync in flash applications? Essentially it would work like the old CCD chips where: the mirror would raise(assuming there is a mirror) and the shutter open, the chip would turn on, the flash would fire, the chip would turn off, and the shutter and mirror would reset. If the sensor could be switched on and off in, say, 1/1000th of a second or faster, it could have dramatic implications for outdoor location shooting. Having the extra DR is already a nice bonus.
Technology sucks, we should all go back to shooting Daguerreotypes. Can't be copied, satisfactorily anyway, and the only way to obtain one is to hire a professional.
Maxfield_photo: On the one hand, it's good that Pentax had decided to fill this gap in their upcoming full frame line up, but $1300 is a lot for a re-branded Tamron design. I owned the Tamron version (think I paid $450 used from KEH), and it was a decent performer, but I was never wowed by the images the way I am with my DA* 50-135. I traded the Tamron for the Pentax FA* 28-70, and I'm very glad I did, it's a magnificent lens. Pentax does not give out the * designation lightly. With the announcement of this stop-gap lens, I have the feeling it may be a long time before we see a D FA* standard zoom for a system that deserves it.
Ah! Actually I stand corrected, this is a copy of the newer Tamron design, 17 elements in 12 groups with 4 asphericals and 3 ED elements. The older design which I owned was 16 elements in 14 groups. THAT lens was much cheaper than the new design. And since this new lens has the Pentax HD coatings $1300 may not be so steep, still it would have been nice to see weather sealing, even if it increased the cost.

Under The Sun: Vote with your hard earned money folks. If you don't like the subscription model taking over don't buy into it. If Adobe makes money over this be assured subscription will be the thing of the future.
Is there any way I can click the like button twice? or ten times?
My K20D does that sometimes. If anyone is experiencing this problem, but doesn't want to send their camera in for service, try pressing the shutter button after the power switch is in the off position. I've gotten in a habit of doing it every time I turn off the camera.
Wow! This looks like a seriously fun lens!
Hopefully they are swapping the zoom and focus rings back to their proper place, though I think that's pretty unlikely.
Greg Lovern: > The 70-200mm is the first full-frame telephoto zoom to bear Pentax's 'Star' designation <
Not true. It's at least the fourth. The first three were:F* 250-600/5.6 (1988)FA* 250-600/5.6 (1991)FA* 80-200/2.8 (1994)
Touché. You really did want to split hairs, LOL
I caught that too, but if you want to split hairs, they did add the qualifier, "...and features a new 'HD' coating." So technically it is correct.
I'm set for a standard zoom with my FA*28-70, but I'll be interested to see a 15-30~ish zoom. The zoom range is narrow, only 2x, but that means there will be less aberration that needs to be corrected at the ends of the zoom range. Any less range though and it wouldn't be worth the space in my camera bag, might as well carry a prime.
My theory: The K-S1 was such a flop that they finally realized it's no good making cameras that people aren't asking for. Instead they decided to pursue the novel idea of actually making cameras people want and have been asking for for years.
I think they may in trouble financially if they had to resort to making a full frame, but ironically, if done right, this camera might be the camera that saves them.
I hope they find the wisdom to steer clear of the "smaller/lighter is better" mentality. A professional body needs a certain amount of weight to counterbalance large zooms like the two companion lenses announced along with this camera. If users want small, light cameras there are plenty of other options on the market. Full frame glass has to be big, full frame bodies should be sized accordingly.
I am excited to see this camera though, whatever in form it eventually takes.
I don't disagree with the logic here, but it is only one take on the subject. I am a Pentax shooter, and so sadly, I am not troubled by the decision to switch to full frame T_T (although I still regularly shoot film).
I would offer a different take on the subject of focal length, of zooms in particular. I own and love a Pentax FA* 28-70 f/2.8 zoom. Obviously it was originally designed to go from wide angle up to short telephoto, and then there was an FA* 85 to serve as the "ideal" portrait length. I find that when I use the lens on my film bodies (i.e. full frame), I live at either end of the focal range. My shots are either below 35mm or above 60mm. But when I get that lens in the studio for fashion shots on my digital APS-C body, I find it is ideally suited to the task. I can frame a tight headshot at 70mm, and a moment later zoom all the way out to 28mm and get my subject head to toe, all without moving, but I also end up using the entire focal range, not just the extremes.
firstname.lastname@example.org: NFC - for those who don't know (which is probably most of us):
Near Field Communication
Bluetooth and Wi-Fi are similar to near field communication on the surface. All three allow wireless communication and data exchange between digital devices like smartphones wirelessly.
NFC is an offshoot of radio-frequency identification. NFC is designed for use by devices within close proximity to each other.
Thanks, didn't know if this was just a case of technology leaving me behind, or just sloppy journalism. I'm still not sure, but at least I know what NFC means now.
AV Janus: This article is in some strange loop.DPR says see more on cactus page, thaz page shows a few pixs an "view more details" link redirects here??
Where is the info that this supports wireless radio TTL?
Uh, well not really flash exposure comp, it's just remote manual power control. The menu system is built into the V6 base unit though, not the camera. There are four groups A,B,C, and D, and you can adjust each group independently, or adjust all groups together in parallel. (e.g. You might set group A at 1/4th power, and group B at 1/8th power, and group C at 1/16 + 0.3. After a test shot you might decide that the whole setup needs to come up a stop, and with one turn of a dial, you can bring group A up to 1/2, group B up to 1/4th, and croup C up to 1/8th +0.3)You can also turn groups on and off, all from the camera position. This is great if you want to see the contribution of an individual light/group. It even allows the user to make adjustments in 1/10th stop increments if they desire (though it does not force one to do so).
akexandrevision: Nice to see finally a Wireless trigger solution for Olympus & Panasonic cameras however I am still confused on some features on this new Cactus V6.
Firstly, Does this support TTL on my Olympus cameras (OMD-EM1, E-30 and E-P3)?I mean can I set my flashes (FL-50R and Fl36-R) on TTL and shoot on TTL or this is only working in manual mode with full control from the trigger on each single Flashes?
Secondly:Can this transceivers wake up the flash from the sleep mode?
thirdly, what is the maximum Sync Speed I can use on the Transceivers.
I appreciate If someone could clarify these for me, I could not find any thing related to my questions on Cactus website.
It's best to think of the Cactus V6 as a manual flash solution. It just happens to exploit the flashgun's TTL circuitry in order to work it's magic. No TTL data is transmitted from the on-camera unit to the remote units, although you can pass TTL data to a hotshoe mounted flash as long as it speaks your camera's proprietary flash language.
The wake-up function may be system dependent, but it is likely that firing a test flash will bring most flashguns out of hibernation.
The maximum speed the Cactus system will relay a signal is 1/1000th, but you will still be limited by your camera's maximum sync speed.
And since you'll probably ask, the V6 does not support true HSS, but it does have a mode called "sympathetic flash" where the V6 will "chime in" with a burst a few milliseconds after it sees a preflash causing the flash tail to illuminate the shot. This is similar to what PocketWizard calls "hypersyncing".
No, you are not comprehending something. The V6 does not just send a "fire now" command the way ordinary manual triggers do. It sends a "fire now" command, and then the base unit uses predetermined timings to send a "stop firing" command through the TTL circuitry several milliseconds later. That's why it needs to know what kind of flashgun is attached. The result is that the user can control the output of the lights from the camera's position.
Cactus is not the first to try this. Radiopopper uses the same TTL circuitry in the RP JrX system to achieve the same effect, but the controls on that system are not particularly precise or repeatable compared to the Cactus.
It really is a revolutionary system for those who take the time to understand it's potential.
It does not. It supports wireless manual control via old TTL circuitry.
That's weird, I've been using my Metz 58 AF2 with my Cactus V6s for months. I wonder what they added?
